On country roads you should dim when oncoming traffic or turn the lamp on the side (you can see the lamp by a few degrees to the right / left turn)
Battery replacement is very easy thanks to solid mechanics. No screws, levering, not susceptible to wear. One should watch out that you do not lose the rear rubber seal.
The supplied bracket is suitable for all handlebar diameters, a tightening only with finger force. When you put on strong, but the bracket is so stable that it does not move during start / disconnecting the lamp and cobblestones. The supernatant should be cut flush, so that no one will hang.
Absolutely water and weather-resistant.
Addendum: I can not confirm that the lamp goes out completely when the batteries have a lower voltage. The lamp will continue to the lower level and is just getting darker. Bin last ride red low battery LED is still on for an hour. Perhaps she goes from some point, but then at a brightness level that would be much too low to drive anyway.
Also, I have now the original - I have described as shaky - holder in use, which is still strong enough in attracting strong.
